If only they would invent paragraph breaks.

Does the solder still use lead and rosin?

How soon can we get a spool of it at Radio Shack? If nothing else, with the lower melting temp, the odds of cooking a semi-conductor you’re soldering goes down even if the soldering iron is set for normal solder.

"Rather than finding another multi-component alloy, our team devised a solution based on the well-known melting point depression of materials in nanoparticle form. Given this nanoscale phenomenon, we've produced a solder paste based on pure copper."

Hard for me to believe how the cost of solder has gone up. I just got to the end of a 1 lb. rosin flux core spool from Radio Shack — probably 15 years old. Now I see that a couple of small winds cost as much as that heavy spool did.
